grasping a wire for`the purpose of drawing it Io 4from oneplace toanother or for stretching it,

designed principally for use-in the placing of telegraph and other wiresupon poles.

My objects are to increase the security of the hold on the wire and theease with `which the wire may be grasped bythe tool; and Vmy inventionconsists in the novel devices and combinations of devices employed by mein accomplishing these objects, as hereinafter set forth and claimed.

My invention is illustrated in the panying drawings, in which- Figure 1is a plan view, and Fig. 2 an endview, of a tool embodying saidinvention.

BJCCOIII- A is a suitable handle adapted to be grasped.

by the hand, and from which extend the stems B B, near the ends ofwhich, at b b, between, lugs a a, are pivoted the grippingjaws or.

cams OC, which are adapted to grasp a wire, as D, between them,and'which have rough- 3O ened or corrugated inner surfaces for thatpurpose. The stems B B are each encircled by a coiled spring, E, which4springs are adapted to be compressed between shoulders c on the stemsand lugs d encircling the stems, which 5 are attached to or form part ofthe plate F,

which slides on said'stems against the springs and upon whichthe jaws CC are pivoted at e c. Upon the wire D being inserted between the jawsthe plate Fis moved back against 4o the springs a greater or lessdistance, according to the size of the wire, and then the pull on thetool, being exerted against the points b b ofthe grippingjaw, brings theinner sides of said jaws against the wire, so as to grip it with apowerful pressure, and the greater the strain on the wire the greaterwill be the gripping force of the jaws. n

I so shape the gripping-jaws or cams that the same lamount of surfacecontact will be 5o given to the wire no matter what the size of i uponthe handle to grasp the wirebetween ,them.

VIn using such an instrument the pullfis di rectly upon the pivotedpoints of 'the jaws,

andthe gripping pressure is due only to this direct pull; but in myinvention, since the handle is'separately connected Vwith the jaws at bb, the pull is exerted at the points other than the fulcruni-points e e,and there is an additional leverage which causes akmuch greater pressureupon the wire, and every additional strain gives acorrespondingly-multiplied addition to the hold on the wire. 'The strainalso tends to draw the sliding plate selves, by their pressure on theplate, force the cams together. e

`WWith my invention, also, it. is much easier to grasp the wire, sinceby pressing the plate against the wire the same is forced back. and thejaws are opened, andthe tool maybe then turned to bring the wire betweenthem, whereupon the wire is at once held rmly by thel jaws,substantially as set forth.

2. In a wire-holding tool, the combination of the handle terminating inbranchingstems,

'away from the handle, and so to increase the pressure on the wire, andthe springs them-y the -plate sliding on said stems, and thegripping-jaws pivoted on said plate and separately connected with saidstems, substantially as set forth.

3. In a wire-holding tool, the combination of the handle terminating inbranching stems,

the plate sliding on said stems, the springs pressing said plateforward, and the grippingjaws pivoted on said plate and separatelyconpeoted with said stems, substantially as set Orth. 1
